BootCamp problem!

I am having a little problem installing windows XP using bootCamp (last version).. When I enter in the ugly blue installation mode where you have to choose: enter to continue installation, r to repair or f3 for help. Nothing works!!! I press enter to try to continue installation nothing.. then I tried others options nothing..

I think the keyboard is disable or something because I tried the num lock key or caps key and I can't obtain the green led!
